FLOOR CONSTRUCTION.

Application filed February 9, 1926. Serial No. 86,992.

This invention relates to certain improve ments in floor constructionsand. has been designed particularly for constructingfloors ofcomparatively small areas, such as houses, apartment houses, and thelike.

As now largely constructed, side or end girders are used of the I-beamtype, that is, girders having upper and lower flanges. These girders actas supports for lighter beams or girders which are positioned betweenthem to form the floor, these lighter beams also acting as supports fora ceiling beneath them. hese floor beams are of metal and are secured tothe girders by riveting. This takes time and adds considerably to thecost of construction.

The main object of the present invention is to produce a floor structurein which the cross beams or floor beams are secured to the side or endgirders by means which are independent of either, so that the floorbeams can be supported from the girders without any rivets and can thusbe put in place quickly and inexpensively.

A further object of the invention is to provide an improved securingdevice by which the floor beams can be supported from the side or endgirders.

With these and other objects not specifically referred to in view, theinvention consists in certain novel parts, arrangements and combinationswhich will be described in connection. with the accompanying drawingsand the novel features pointed out in the claims hereunto annexed.

. In these drawings,

Figure 10 is a plan view of the beam section shown in Fig. 11;

Figure 11 is a perspective view of the modified form of beam sectionshown in Fig. 9, and

Figure l2is a detail sectional View of a beam section which may beemployed where it is desired to support the floor beams below the mainbeams.

Referring now to these drawings and first to Fig. 1, the main side orend beams'or girders are indicated by the numerals 1,

2. These are of I-construction, having top flanges 3 and bottom flangesi, and these beams are supported from any suitable sup port or standard,not illustrated. These main girders support the floor beams, marked 5, wich extend between the main beams,

three such beams being shownin Fig. 2.

In the construction shown in these figures it may be assumed that a oneroom wide floor 18 being constructed. In accordance with the invention,means are provided whereby the floor beams may be supported from themain side beams or. girders without riveting, the securing means beingindependent of the girders and the floor means. While these beams mayvary to a considerable extent in character, in the particularconstruction shown, short beam sections are provided which lock aroundunder a flange of the main beams and supportthe floor beams, the floorbeams simply resting on these sections, these sections being in effectshort cantilever beams which take the load thrust of the floor beams. Itwill be understood, of course, that the beam sections have suflicientstrength to support the weight of the floor beams and the expected loadwhich the floor beams are to carry.

These beam sections may vary widely in form and construction. In theparticular construction illustrated, however, and referring first toFigs. 1 to 6, there is provided a beam section having sides 6, 7 and anda base 8. i The floor beams are provided with an upper flange 9 andpreferably a lower flange 10, from which a ceiling structure may besupported. The sides 6, '7 of the section lie beneath the edges of theflange 9 of the floor beams, the floor beams resting on these flanges.The beam sect-ion may be secured to the main girder in various ways. Asshown, the beam section is formed by bending over the base at the troutto form a locking tongue 11, which is turned around and under one side,as 12, 01 the top flange ot' the main girder. Means are provided forpreventing sidcwise displacement of the section, which may be in theterm of a narrow tongue 13 which is bent around under the opposite edge1% of the main side beam.

It will be observed that the web of the floor beam is positioned in theslot 18 formed by cutting out the tongue 13. This prevents any lateralmovement of the beam and as the beam is supported on each edge of thebeam section any tipping or rocking of the beam is effectuallyprevented.

lVith this construction it will be seen that the floor beams may veryreadily and quickly be positioned without requiring any riveting or anyother securing devices, and by simply placing them in position on thesections, the sections having been secured to the girders. It will beunderstood, of course, that a section will be provided for each end of afloor beam, as shown in Fig. 1.

l/Vher'e a floor is to be assembled in which the floor beams are locatedon each side of the main girder, a section such as shown in Fig. 7 maybe employed. In this section locking tongues 15, 16 are cut out from thebase at opposite ends of the section, and these are bent around theedges 12 and Lt of the flange 3 of the main girder. The section isdimensioned so to extend beyond the girder at each side and thus cansupport the adjacent ends of two floor beams. v

If desired, the sides 6, 7 of the section may be turned in, as indicatedat 17 in Fig. 11, to form ledges on Which the flange 9 may rest. A slot,as 18, may be left through which the web 20 of the floor beam may pass.

With the construction so far described, it will be seen that the floorbeams are supported somewhat above the main girders.

Under some circumstances, it may be desirable that they be supportedbelow, and in Fig. 12 a section for eflecting this is provided in whichthe section is formed with a downwardly extending extension 21 on whichthe floor beams rest, the side play of the section being prevented byforming the downwardly extending part with an acute angle, as indicatedat 22, this forminga stop and preventing displacement of the hangeiulVhile the invention has been shown and described in'what is believed tobe its best forms, it will be understood that certain chan es andvariations may be made in the specinc construction of the hanger withoutdeparting from the invention as defined in the appended claims.

What I claim is:

1. In a floor construction, the combination of side or end I-girders, abeam section hav ing a part engaging the top surface of the girder and apart extending laterally from the girder and forming a flanged beam seatclear of the web of the girder, and an I- tloor beam supported by itsupper flanges on the flanges of the beam section, said beam sectionbeing held in place by bending a part thereof under the top flange ofthe girder.

2. In a floor construction, the combination of side or end I-girders, abeam section having a part engaging the top flange ot the girder andportions extending laterally on each side of the girder and clear of thegirder web, and I-floor beams supported by section, said beam sectionbeing held in posi tion by bending parts thereof under the top flangesof the girder. I

3. A beam section for supporting I-floor beams having a part arranged tolockingly engage the top surface of the girder and laterally extendingflanged portions on each side thereof on which floor beams may besupported, and locking tongues for locking the beam section to the topflange ot' the girder.

In testimony whereof, I have hereunto set my hand.
